Application filed October 3, 191. Serial No. 123,486.

To all whom/t may concern: Be it known that I, JAMES. I. PRIMM, a citizen of the United States of America, and

a resident of Tampa, Hillsborough VVcounty,l

and State of Florida, have invented certain new and useful Improvements in Elevator- Guide Lubricators,pof which thefollowing is a specification, reference being had'to the accompanying drawings, Vforming a partv thereof.

' My invention relates toimprovements in elevator guide lubricators, and its object is to improve uponsuch devicesas havexbeen available heretofore and to provide aA simple, inexpensive and eflicient device which is capable of applying the neededlubrication to the guides of elevator cars or counterweights, without loss and with but the minimum amount of attendance.

Theseand other objects of the invention will be set forth in the following specification in which I will describe my invention, the novel features of which will be set forth in appended claims.

4.Referring to the drawings:

Figure l is a top plan view of an elevator guidelubricator which is madeaccording to and embodies my invention. y

Fig. 2 is a sectional elevation of the left hand portion of the apparatus shown in Fig. 1, it being understood that the right hand portion is similar in construction and arrangement to the parts shown. Y'

Fig. 3 shows a half of one of the guide brushes, this figure being a perspective view of a brush cut through its center on a plane represented by the cross-hatched surface.

Fig. d is an elevation of one of the upper corners of an elevator car with one of my improved lubricators applied thereto, together with aportion of an elevator guide which is to be lubricated.

' Like characters of reference designate corresponding parts in all the figures.

10 designates the main bodyof the lubricator. This part is hollow'and forms a reservoir for the oil 11 and also -forms a support for the other parts ofthe device. It hasV substantially the form of a rectangular box with a square recess 12 provided in one of its sides.

13 is a cover plate which fits over the body and closes the reservoir. This is provided with a filler opening covered by a cap 14.

Left and right hand brushholders 15 and( leachwith a flange on its inner side, are

aixed to the cover plate on opposite sides of the recess 12, and another brush holder 17 of similar construction but with a` flange on each of its sides, is-aiiixed to the cover plate on the remaining side of the recess.

All these parts are constructed preferably of metal such for example as aluminum alloy and fastened together by screws, bolts or other suitable devices. 1

In each brush holder is an'elevator guide brush 19 of cross section to form arslidable fit in the brush holders. rlhese are pressed into engagement with the elevator guide 20 by compression springs 21. rIhese brushes preferably are constructed of wood fiber.

Their faces which are pressed against the guide are parallel with the surfaces of theV guide and in intimate contact therewith. In each ofthese faces is a transverse oil groove 22 whichdoes not'extend to the ends of the surface of Ythe guides.l The groove 22A in the brush in brush vholder 17 is shorter than those in the others because the end surface of the elevator guide is narrower than the side surfaces thereof.

'Ihe` brushes are further provided with holes 23 which extend from thev oil grooves through the underl side of the brushes.

WicksQL arepfitted into these holes and held thereby. One end of each wick terminatesl at 25, before lit reaches the oil groove so that each oil groove forms Va closed oil chamber. The other ends dipinto the oil 11. Slots 18 are providedin the cover plate 13 to allow for the lpassage of the wicks into the reser-` voir and to permit a longitudinal movementA Y i of the brushes.

The device is easily attached to the top guide shoe of an elevator car or its counterweights, or to the car frame itself, by suitable brackets. When in place oil willbe raised from thereservoir into the little inclosed oil chambersfby capillary action, but

can not 'escape while the car is at rest be cause the oil chamber excepton its wick side, is entirely closed by solid surfaces.

4.When the car moves however, a very thin film of oil will be left on the surfaces of the guide, but the flat surfaces of the brushes prevent the application of an over-supply. These surfaces Vof the brushes also prevent the adhesion of any foreign matter to the surfaces of the guides and further serve to give an even distribution of the lubricant. I have found that this devicesaves labor, oil
